FASTENING FOR THE MEETING-RAILS OF SASHES.

SPECIFICATION forming .part of Letters Patent No. 229,894, dated July13, 1880.

(ModeL) To all whom it may concern:

Be it known that we, ADAM KOLB and CHARLES OSBERGHAUs, of Sandusky, inthe county of Erie and State ofOhio, have invented a certain new andImproved Fastening for the Meeting-Rails of Sashes; and we do herebydeclare that the following is a full, clear, and complete descriptionthereof.

The nature of this invention relates to a to window fastener or look bywhich the upper and lower sash can be securely fastened to prevent theirbeing opened from the outside. The fastener at the same time binds thetop rail of the lower' sash firmly to the lower rail ot' the upper sash,thereby preventing drafts of air, rain, snow, and dust from passing inbetween said rails. The fastener also not only prevents the sash fromrattling, but may be applied to the sash for holdingit raised at anydesirable height.

The window-lock alluded to consists of a sliding bolt, which, when in acertain position, is given a horizontal rotative movement by liftin gthe end of a key projecting from the outer 2 end of the sliding bolt,which allows the said bolt to be pushed forward and turned laterally forlocking the two sashes together.

A more full and complete description of the invention is as follows,reference being had to 0 the annexed drawings, making a part of thisspecification, in which Figure 1 is a front View of the sash-fastener.Fig. 2 is a side view of the lock. Fig. 3 is a plan view. Figs. 4, 5,and 6 are detached sec- 5 tions. Fig. 7 is a-transverse verticalsection.

Like letters of reference refer to like parts in the several views.

In the drawings, A represents the sliding bolt above alluded to, adetached view of I 4.0 which is shown in Fig. 4. Said bolt is hollow,

an annular rib, I, within which the bottom of key from moving forwardout of place. The 5 opposite end of the key projects through the end ofthe bolt and terminates in a thumbpiece, O, whereby the key is operated,as and for a purpose presently shown. On the under side of the key is anib, c, Fig. 7, of a size to fit in the holes (I and (1, made in thebottom plate, D, Fig. 5. In the key is also a slot, an, corresponding tothe slot at in the sliding bdlt. H is a shell or cap partially coveri ngthe bolt, through which the bolt slides reciprocally and turnshorizontally therewith for engaging and locking together the sash. Saidcap stands upon the base-plate I.) alluded to, and is retained thereonfrom lateral displacement by 6 the cap fits. The cap is prevented fromleav- 5 ing the base-plate by a screw-bolt or pin, J, passing downwardthrough the said cap, sliding bolt, and key, and screwed into thebaseplate, substantially as shown in Fig. 7. On the base-plate referredto, and within the annular rib, is fixed a cam, n, Fig. 5, the purposeof which will presently be shown.

B is a catch arranged to engage the book 0, terminating one end of thesliding bolt alluded to.

The practical operation of the above described device is as follows: Tothe upper rail of a lower sash, a section of which is represented at K,is secured the lock or fastener by means of the base-plate and screws 6,Fig. 3. To the lower rail of the upper sash is fixed the catch 13 insuch relation to the look as shown in the drawings, in which Mrepresents a section of the lower rail of anupper sash.

' In Fig. 3 the two rails, though represented as being a little distanceapart, may be drawn together and locked. In this relation of the tworails the sliding bolt is shown as drawn back, so that the lower sash,K, can be raised or the upper one, M, lowered. The bolt is retained.thus drawn back by thenib c of the key B, lodged in the, hole at, Fig.5, in the. base-plate. Said nib prevents the bolt from sliding endwiseand laterally. The bolt and key move together by the engagement of thefinger a and nib 0, above described.

In order to lock the two sashes together the bolt is pushed in. To dothis the nib 0 must be lifted from the hole [1. To this end the key B israised upward by placing the finger upon the knob or thumb-piece O andpressing it upward, thereby withdrawing the nib from the hole. Thesliding bolt can now be pushed forward until the lug b on the side ofthe bolt comes to the cam n, Fig. 5. This movement of the bolt bringsthe notchm, Fig. 4, in the side thereof in open relation to the annularrib I, and allows the bolt to be turned laterally in either direction.

When the bolt has been pushed in the hook Gthereof will be in the catchB. Now on turning the bolt in direction of the arrows the hook will passalong under the curved edge a of the catch, as seen in Figs. 2 and 7. Asthe bolt continues to turn, the cam a and the nib I) act as a pivotalpoint for the further rotative movement of the bolt, and, on account ofthe said pivotal point being eccentric to the axial line of the eapsrotative movement, the bolt will be drawn back while the cap turns onits own axis. This backward action of the bolt draws upon the catch andbrings the rail M in close contact with the rail K. The two sashes thusbroughttogether are shown in Figs. 2 and 7. The two sashes, when broughttogether as described, bring the bolt at right angles across the rails,as seen in Fig. 2, instead of in an oblique position, as seen in Fig. 3.

When the sashes are closed together the bolt is prevented from movinglaterally and endwise by the nib e of the key, which in this position ofthe bolt will be lodged in the hole d. of the base-plate, as shown inFig. 7. The

two sashes thus locked together cannot be released until the nib e islifted from the hole,

which is done by pushing upward'the knob O, which permits a reversemovement of the sliding bolt for unlocking the sashes.

The application of the lock to the sashes, as above described, preventsthem from being opened without a manipulation of the look.

For the purpose of holding up the sashes at any particular height a lockis secured close to the end of the rail K, so that the bolt, when pushedforward, will enter the catch D attached to the side rail, 0, of theupper sash. 0n raising the lower sash so that the bolt of the lock mayengage the catch D,- it is then the catch. The bolt is then turnedlaterally, that the hook ot' the bolt may engage the edge h of thecatch, and thereby hold up the sash and prevent it from being raised orlowered without first manipulating the look, as above described, forunlocking the two sashes.

What we claim as our invention,'and desire to secure by Letters Patent,is-

1. In sash-locks, a hollow sliding bolt provided with a hook, C, and lug1), key B, and nib c, in combination with the base-plate, having thereinholes d cl, adapted to receive the nib of the key, and cam a,substantially as described, and for the purpose set forth.

2. In combination with the hollow sliding bolt A, and key B within thebolt, and lug b, the base-plate, having thereon a cam, 02, substantiallyas and for the purpose specified.

In testimony whereof we aflix our signatures in presence of twowitnesses.
